The Pico Technology PicoScope 4424 is a 4-channel USB oscilloscope delivering 12-bit vertical resolution, upgradeable to 16-bit via Resolution Enhancement, for precision measurement of low-level and noise-laden signals. Operating at 20 MHz bandwidth with 80 MS/s sampling and 256 MS capture memory, it combines portability through USB 3.0 connectivity with laboratory-grade signal fidelity. The integrated 14-bit Arbitrary Waveform Generator and advanced triggering system—including runt pulse detection, dropout monitoring, and 4-input Boolean logic—enable sophisticated test and validation workflows without external instrumentation.
